The barbell rollout is a premier anti-extension core exercise that builds exceptional abdominal strength and stability while engaging the lats and shoulders. It challenges the core to maintain a neutral spine against gravity as the lever arm increases during the extension.

Setup
- Kneel on a soft mat with a barbell loaded with round plates positioned directly in front of your knees.
- Grip the barbell with an overhand grip, slightly wider than shoulder-width apart.
- Position your shoulders directly over the barbell with your arms fully extended and your weight on your knees.
- Engage your core and tuck your pelvis into a slight posterior tilt to flatten your lower back.
How to do it
- Inhale and slowly roll the barbell forward, extending your body into a straight line as far as you can while maintaining a neutral spine.
- Keep your arms straight and your core braced throughout the entire descending range of motion.
- Exhale and pull the barbell back toward your knees by forcefully contracting your abs and lats.
- Maintain a controlled tempo, taking roughly 3 seconds to roll out and 1-2 seconds to return to the start.
Form checklist
- Avoid letting your lower back arch or sag toward the floor at the bottom of the movement.
- Keep your elbows locked or slightly soft; do not bend them to pull the weight back.
- Stop the forward roll immediately if you feel tension shifting from your abs to your lower back.
- Ensure your hips move forward in sync with your torso rather than leaving your glutes behind.
Pro tips
- Focus on maintaining a 'hollow body' position by actively crunching your ribs toward your pelvis throughout the set.
- Initiate the return phase by driving your navel toward your spine and pulling through your armpits to maximize lat and serratus involvement.
Make it harder
- Add a 2-second pause at the point of maximum extension to increase time under tension.
- Perform the movement from a standing position instead of kneeling to significantly increase the load on the anterior chain.
